Does anyone know what standard the rosette mount on the DJI Focus Handwheel 2 is meant to be?  It seems to be 28mm diameter with 60 teeth, which is odd given that the Osmo normal rosette seems to be 20mm diameter with 30 teeth.  The Handwheel will go on to a Osmo rosette mount with the 1/4" bolt tightened but the teeth don't engage properly. I know the ARRI standard is 31.8mm diameter and 60 teeth,  and the RED standard is 28mm but with fewer teeth.

We will confirm with our engineers about the size, since the Handwheel is also compatible with Inspire 2, the size may be different as the Osmo normal rosette, please mount with 1/4" bolt as long as it is tight.
